These may vary WILDLY because of random alterations made by the manufacturer from batch to batch, gas pressure, ambient temperature, battery charge and so on. Some of the figures therefore should be treated as a very loose guide or indication only, based on the spot tests we have performed. The images and product contents listed are again based on a spot check we performed at a given point in time, and may differ due to changes, omissions or inclusions made by the manufacturer. If you require something specific, such as FPS, you MUST specify this at time of ordering, and take a tuning option where required.
